Dipeptidyl-peptidase-IV by cleaving neuropeptide Y induces lipid accumulation and PPAR-γ expression.

We evaluated the effects of dipeptidyl peptidase-IV (DPPIV), and its inhibitor, vildagliptin, on adipogenesis and lipolysis in a pre-adipocyte murine cell line (3T3-L1). The exogenous rDPPIV increased lipid accumulation and PPAR-γ expression, whereas an inhibitor of DPPIV, the anti-diabetic drug vildagliptin, suppresses the stimulatory role of DPPIV on adipogenesis and lipid accumulation, but had no effect on lipolysis. NPY immunoneutralization or NPY Y(2) receptor blockage inhibited DPPIV stimulatory effects on lipid accumulation, collectively, indicating that DPPIV has an adipogenic effect through NPY cleavage and subsequent NPY Y(2) activation. Vildagliptin inhibits PPAR-γ expression and lipid accumulation without changing lipolysis, suggesting that this does not impair the ability of adipose tissue to store triglycerides inside lipid droplets. These data indicate that DPPIV and NPY interact on lipid metabolism to promote adipose tissue depot.

Informe sobre el IV Congreso ISKO-España, EOCONSID'99 (Granada,22-24 d'abril de 1999)

El quart EOCONSID (Encuentro de Organización del Conocimiento en Sistemas de Información y Documentación), organitzat per ISKO-España (Capítulo Español de la International Society for Knowledge Organization), ha suposat «situar en el mapa» un congrés i una entitat que fins ara havien tingut poca projecció. Tot i organitzar les trobades regularment ¿cada dos anys¿ des del 1993, el poc coneixement de l'entitat i dels seus objectius comportava una assistència escassa de professionals a les trobades, limitada, es podria dir, als membres de l'entitat i als alumnes de la Universidad Carlos III, ¿entitat que havia acollit les segones i terceres trobades. Igualment, les actes publicades tenien poc ressò, tot i incloure contribucions d'un bon nivell de qualitat. El canvi en els òrgans de govern d'ISKO-España, el 1998, va replantejar la manera d'organitzar el congrés: es va decidir formar un equip independent de la junta directiva que s'hi pogués dedicar plenament i que garantís un major grau de professionalitat.

Diagnostic value of MRI for the detection of suspected placental invasion: Does it depend on observers' experience?

Purpose: To evaluate the diagnostic value of specific MR features for detection of suspected placental invasion according to observers' experience.Methods and Materials: Our study population included 25 pregnant women (mean age 35.16) investigated by prenatal MRI. In twelve out of them placental invasion was histopathologically proven, the 13 other women (52%) without placental invasion served as control group. Multiplanar T1- and T2-weighted sequences had been performed mostly without IV contrast injection (1.5 T). MR examinations of the two groups were rendered anonymous, mixed, then independently and retrospectively reviewed by two senior and two junior radiologists in view of 8 MR features indicating placentar invasion including the degree. Results were compared with surgical diagnosis (placenta normal/increta/accreta/percreta). Interobserver agrement between senior and junior readers were calculated. Stepwise logistic regression and receiver operating (ROC) curvers were performed.Results: Demographics between the two groups were not statistically different. Overall sensitivity and specificity for detecting placentar invasion was 90.9% and 75.0% for senior readers, and 81.8% and 61.8% for junior readers respectively. The most significant MR features indicating placentar invasion were T2 hypointense placental bands, followed by placenta praevia, focally interrupted myometrial border, posterior placental insertion, and heterogeneous placental signal. For each of the evaluated MR features the interobserver agreement kappa between the two senior readers was superior than that between the junior readers, ranging from bad (<0.4) to good (0.4-0.75).Conclusions: MRI can be a reliable and reproducible tool for detection of suspected placentar invasion, however very variable according to the observers' experience.

Scores composites CHC pour le WISC-IV: Normes Francophones

Bien que le manuel du WISC-IV fasse référence à la théorie de Cattell-Horn-Carroll (CHC), les indices calculés à partir de cette batterie (ICV, IRP, IMT et IVT) n'ont pas été définis sur la base du modèle CHC. Afin d'apporter un éclairage complémentaire sur les performances observées, nous recommandons néanmoins d'examiner les scores des subtests du WISC-IV en référence à la nomenclature des aptitudes cognitives proposées dans le modèle CHC. La première partie de cet article présente les normes francophones pour cinq facteurs CHC du WISC-IV, à savoir le raisonnement fluide (Gf), compréhension-connaissances (Gc), le traitement visuel (Gv), la mémoire à court terme (Gsm) et la vitesse de traitement (Gs), établies en utilisant une procédure d'approximation statistique. La seconde partie présente l'examen de la validité de ces normes, confrontées à des données recueillies sur un échantillon de 250 enfants. Nos résultats montrent que les corrélations entre les indices classiques du WISC-IV (ICV, IRP, IMT et IVT) et les scores composites CHC sont élevées, attestant de la validité des scores CHC. Ces normes permettent de calculer et d'utiliser les scores composites CHC en complément des indices standard, dans le cadre d'analyses normatives et ipsatives.
